LOCK-HINGE.

SPECIFICATION forming part of Letters Patent No. 400,540, dated April 2, 1889. Application filed November 27, 1388. Serial No. 292,043. (No model.)

T all whmn it may concern.-

Be it known that we, BENJAMIN F. BOUGHN,

of Randolph, in the county of Cedar and State of Nebraska, and WILLIAM CASHNER, of Pleasant Hill, in the county of Cass and State of Missouri, have invented a new and useful Iniprovement in Lock-Hinges, of which the following is a specification. I p This invention is an improved lock-hinge; and it consists in certain novel constructions and combinations of parts, as will be hereinafter described and claimed.

In the drawings, Figure 1 is a face view'of our hinge. Fig. 2 is a section on about line a: 00, Fig. 1. Fig. 3 shows the parts of such hinge detached. Fig. 4 is a face view of a somewhat difierent construction of hinge. Fig. 5 is a section on line y y, Fig. 4. Fig. 6 shows a different form of knuckle. Fig. 7 is a detail view of'one of the sections, and Fig. 8 shows a somewhat different construction.

The hinge consists, broadly, of two sections, A and B, a pintle, 0, connecting such sections, the knuckles of section A being exteriorly non-circular in cross-section, and the section B having a spring-actuated bearing-plate, D, pressing against such non-circular knuckles, and the casing E, in which said plate D and its actuating spring or springs operate, the

construction being more specifically described hereinafter.

In the construction shown in Fig. 1 the section A has knuckles-F F and G, the latter being arranged between the knuckles F. The knuckles F are made exteriorly non-circular in cross-section, providing faces 1, 2, and 3, which receive the pressure of plate D, such plate, in contact with faces 1, 2, and- 3, serving to hold the door, gate, shutter, &c., respectively, closed, half-open, or wide open. The said knuckles F are preferably slotted at-f to receive the eye portions 9 of rods G, which extend to and connect with back plates, H, against which the actuating-springs I bear, such connection being preferably by threading the rods Gin plates H, so such connection may be adjusted to increaseor reduce the tension of the springs. Except for this adjustment, it will be understood that the plate H might simply be the cast back plate of the box-like casing E, in which the springs and bearing-plate are arranged to operate. The bearing-plate D'has portions k arranged to bear against the non-circular knuckles F, such parts It being provided with openings in,

through which the rods G pass, the springs I bearing between plates H and D.

In the construction shown in Fig. 3 we arrange a coil-spring on each rod G andone between said rods. It will be understood, however, that one knuckle, a bearing-plate, and a single spring actuating same may be used with good results, or that the number'of the springs or the strength of the same may be increased and suited to the work to be done.

The hinge-sectionsAand B may be secured, respectively, to the door, gate, or shutter and the door-jamb, gate-post, or window-jamb in any suitable manner. It is usual, to such end, to provide the sectionA with a flange,A, and the section B with a flange, B.

The flange B might be omitted and the section secured by screws passed through casing E, as indicated by dotted lines 4, or by end or side flanges, as indicated in dotted lines 5 and 6.

In Fig. 3 the knuckles F are shown with face 2 at right angles to faces 1 and 3 and the corners slightly rounded. Fig. 5 shows a similar construction of knuckles, except that the corners are more abrupt, While Fig. 6 shows a somewhat oval form of knuckle F. The square knuckles may be preferred for housedoors, gates, &c., and the oval form for shutters. In the construction shown in Fig. 4 the pintle has a flat head convenient in the flush hanging of the hinge. In the construction shown in said Fig. 4 the spring-rods G connect with the bearing-plate and move, in the operation of the device, through openings in the back plate, H, and within sockets or recesses formed for them in the jamb or post, as will be understood from Fig. 5.

The pin or pintle may be changed to reverse the hinge. In use as a surface-hinge any desired ornamental design or pattern may be employed. The constru stion as understood from the drawings is simple and easily attached, substantial, efiective in operation, and may be manufactured and put on the market ready for application to doors, shutters, gates, or elsewhere where it is desired to use the improvement.

In the construction shown in Fig. 8 the section A has but a single knuckle and the section 13 has two knucklesone at each end the knuckle of section A fitting between those of sect-ion B, as shown, and the bearing-plate being made straight and the knuckle of sec tion A bearing flat thereagainst, as shown.

Having thus described our invention, what combination of the section A, having knuckles F, provided with slots f, the section B, having box-like casing E, the back plate and the bearing-plate in such casing, a spring or springs between said plates, the rods G, having perforated heads g fitted in slots f, such rods being passed through the bearing-plates and connected with the back plate, and the pintle passed through the knuckles of sections A B and through the heads of rods G, substantially as set forth.

3. The combination of the section A, having a knuckle or knuckles exteriorly non-circular in cross-section, the section B, the pintle connect-in g said sections, the bearing-plate, the back plate, the spring or springs bearing between said bearing and back plates, and

the rod or rods G, connected with the pintle,
